Interearth consists of five kingdoms: Colmador, Ajer, Alhamr, Engort, Nermutan. They constantly quarrel with each other, uniting in strange alliances, and allies in previous wars could be enemies, and former enemies can become allies. There is no witchcraft, magic, dragons, elves, gnomes, orcs and other characters typical of the fantasy genre. Interearth is inhabited by people. They are different: good and evil, brave and cowardly, noble and vile, greedy and generous, living in the early Middle Ages. For everyone, the East is the unknown Land of Membra, separated from Interearth by high impassable mountains or an endless hot desert. In this world there are two main religions - Revelations of the Forerunners and the canons of the Teachings of the Three Great Ancestors. According to ancient legends, in time immemorial they were brought by gods who descended from Heaven. No one remembers what the gods looked like, only legends about them remain. Adherents of one religion mortally hate adherents of another. In addition, there are different movements in the main religions, which is also a stumbling block between believers who hate not only infidels, but also heretics. Wars in Interearth are common, but wars for faith are the most bloody and cruel. The main character, the Colmadorian Earl Sur, was raised in a monastery until he was twenty, after which the teacher lets him go with good parting words. Earl has to learn that he is the son of those who died in the battle for twenty years back King Colmador - Atual the Third Saorling and Queen Siola from the Warburg family. The young man faces difficult trials: unhappy and unrequited love; captivity after a lost battle and doomed to death by impalement; miraculous salvation; humiliating slavery and salvation again; the fate of an assassin and a damp dungeon; a new sentence of lifelong exile to the galleys and release by pirates; return to their homeland and numerous battles for their father’s throne with enemies who killed their parents and captured Colmador.
